Abstract
Un procedimiento de descodificación de datos de vídeo, el procedimiento que comprende: recibir una unidad de acceso que incluye un conjunto de primeras imágenes en las primeras capas de codificación de vídeo respectivas y una segunda imagen en una segunda capa de codificación de vídeo diferente de las primeras capas de codificación de vídeo, en el que el conjunto de primeras imágenes incluye todas las imágenes en la unidad de acceso que no son imágenes de actualización instantánea del descodificador, IDR, y la segunda imagen es una imagen IDR; y, para cada primera imagen del conjunto de primeras imágenes: i) recibir un elemento sintáctico indicativo de si al menos una porción del valor de contador del orden de imágenes, POC, de la primera imagen se debe restablecer en un valor de cero, ii) cuando el valor para el elemento sintáctico indica que la porción del valor de POC se debe restablecer en el valor de cero, restablecer al menos la porción del valor de POC de manera que la porción del valor de POC sea igual a cero, en el que, antes de restablecer el valor de POC, el valor de POC para la primera imagen es diferente de un segundo valor de POC para la segunda imagen, y iii) descodificar datos de vídeo usando el valor de restablecimiento de POC, en el que un POC es una variable asociada con una imagen que identifica de forma única la imagen asociada entre imágenes en una secuencia de vídeo codificada, y en el que una unidad de acceso incluye todas las imágenes codificadas asociadas con el mismo tiempo de salida.A method of decoding video data, the method comprising: receiving an access unit that includes a set of first images in the respective first video coding layers and a second image in a second video coding layer different from those video coding first layers, wherein the first picture set includes all pictures in the access unit that are not decoder flash update pictures, IDR, and the second picture is an IDR picture; and, for each first image of the set of first images: i) receive a syntactic element indicative of whether at least a portion of the image order counter value, POC, of the first image should be reset to a value of zero, ii ) when the value for the syntactic element indicates that the portion of the POC value should be reset to the value of zero, reset at least the portion of the POC value so that the portion of the POC value equals zero, in the that, before resetting the POC value, the POC value for the first picture is different from a second POC value for the second picture, and iii) decoding video data using the POC reset value, in which a POC is a variable associated with an image that uniquely identifies the associated image between images in an encoded video sequence, and in which an access unit includes all associated encoded images with the same output time.
